[0094] To better understand the embodiments of this application, the following is combined with... Figures 1 to 16 The embodiments of this application will be described in detail.

[0095] like Figures 4 to 11 As shown, this application provides a battery cell feeding device 1 for feeding battery cells 7 into a cup 8. The battery cell feeding device 1 includes: a holding component 11, a pressing component 12, and a guiding component 13. The holding component 11 includes a first holding member 111 and a second holding member 112 spaced apart along a first direction X. The first holding member 111 is used to hold the cup 8, and the second holding member 112 is used to hold the battery cell 7. The pressing component 12 is movably disposed along the first direction X on the side of the second holding member 112 opposite to the first holding member 111. The pressing component 12 includes a pressing member 121 and a protrusion 122. The pressing member 121 is disposed relative to the second holding member 112 along the first direction X. The guiding component 13... The second direction Y is located on the side of the pressing component 12 near the protrusion 122. The guiding component 13 is provided with a guiding groove 131 extending along the third direction Z. The protrusion 122 is located in the guiding groove 131. The guiding groove 131 includes a first groove 1311 whose distance from the second holding member 112 gradually decreases along the first direction X, so as to drive the protrusion 122 to move along the first direction X, thereby pressing the battery cell 7 into the cup 8 along the first direction X. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0096] The battery cell 7 can be a lithium-ion battery, a lithium-sulfur battery, a sodium-lithium-ion battery, a sodium-ion battery, or a magnesium-ion battery, etc., and this application embodiment does not limit this. The shape of the battery cell 7 can be cylindrical, flat, cuboid, or other shapes, etc., and this application embodiment does not limit this either.

[0097] The support cup 8 refers to the component used to support the battery cell 7. Specifically, the side of the support cup 8 closest to the battery cell 7 has a battery cell receiving part for accommodating the battery cell 7. One end of the battery cell 7 is inserted into the battery cell receiving part along the first direction X, thereby achieving support of the battery cell 7 by the support cup 8. By inserting the battery cell 7 into the support cup 8, on the one hand, the uniform specifications and shape of the support cup 8 can be used to easily cooperate with various automated transportation devices (such as conveyor belts, robotic arms, etc.), thereby achieving rapid and accurate transportation of the battery cell 7 between different workstations and improving production efficiency; on the other hand, the support cup 8 can fix and constrain the battery cell 7, keeping it in a relatively stable position and posture within the support cup 8, facilitating precise positioning and operation of the battery cell 7, and thus ensuring the quality and consistency of battery cell 7 production.

[0098] The holding component 11 refers to a component for holding materials, and includes a first holding member 111 for holding the cup 8. In some embodiments, the first holding member 111 can be a mechanical gripper, which opens and closes multiple movable claws to grasp and release materials. In other embodiments, the first holding member 111 can also be an adsorption member, which uses adsorption force to adsorb and fix the cup 8. It should be noted that in this case, the adsorption member can be a negative pressure device, which uses negative pressure generated by drawing negative pressure on the first holding member 111 to adsorb and fix the cup 8; when the cup is made of a magnetic material such as iron, the adsorption device can also be a magnetic device, which uses the magnetic force generated by an electromagnet or a permanent magnet to adsorb and fix the cup 8.

[0099] The holding assembly 11 also includes a second holding member 112 for holding the battery cell 7. Similarly, in some embodiments, the second holding member 112 can be a mechanical gripper, which can grasp and release materials by driving multiple movable claws to open and close. In other embodiments, the second holding member 112 can also be an adsorption member, which uses adsorption force to adsorb and fix the battery cell 7. It should be noted that in this case, the adsorption member can be a negative pressure device, which uses negative pressure generated by drawing negative pressure on the second holding member 112 to adsorb and fix the battery cell 7; when the battery cell 7 is made of a magnetic material such as iron, the adsorption device can also be a magnetic device, which uses the magnetic force generated by an electromagnet or a permanent magnet to adsorb and fix the battery cell 7.

[0100] By setting the first holding member 111 and the second holding member 112 to hold and fix the cup 8 and the battery cell 7 respectively, the battery cell 7 and the cup 8 are set in a corresponding manner along the first direction, so that when the subsequent pressing component 12 pushes the battery cell 7 to move, the battery cell 7 can be accurately inserted into the cup 8, thus ensuring the accuracy of the battery cell 7 feeding.

[0101] The pressing assembly 12 is a component used to press the battery cell 7 into the cup 8 along the first direction X. The pressing assembly 12 is movably disposed along the first direction X on the side of the second holding member 112 opposite to the first holding member 111. When the pressing assembly 12 moves along the first direction X, it first approaches the second holding member 112, thereby pushing the battery cell 7 held in the second holding member 112 to move along the first direction X, and finally inserts it into the cup 8 held in the first holding member 111, thus realizing the feeding of the battery cell 7. The movable arrangement of the pressing assembly 12 along the first direction X can be achieved by a guide rail slider mechanism, or by a lead screw or other mechanism; this embodiment does not limit this.

[0102] Specifically, the pressing assembly 12 includes a pressing member 121 and a protrusion 122. The pressing member 121 is disposed relative to the second holding member 112 along the first direction X. That is, the pressing member 121 is disposed in the first direction X corresponding to the battery cell 7 held in the second holding member 112, so that when the pressing assembly 12 moves closer to the holding assembly 11 along the first direction X, the pressing member 121 pushes the battery cell 7 to move along the first direction, thereby inserting the battery cell 7 into the cup 8.

[0103] In some embodiments, a buffer portion may be provided at the end of the press-in member 121 away from the protrusion 122. The buffer portion is made of a soft material such as rubber to reduce damage to the battery cell 7 when it is pushed.

[0104] The protrusion 122 is disposed at one end of the ejector 121 away from the holding assembly 11. The protrusion 122 is disposed in the guide groove 131. By setting the trajectory of the guide groove 131, the protrusion 122 can be moved along the first direction X, thereby pushing the ejector 121 to move along the first direction X, and thus inserting the battery cell 7 into the cup 8.

[0105] In some embodiments, the protrusion 122 can also be a roller, that is, the protrusion 122 is a cylindrical member that can rotate along its own axis. In this way, when the protrusion 122 moves along the guide groove 131, it can roll within the guide groove 131. That is, the sliding friction between the protrusion 122 and the guide groove 131 can be converted into rolling friction, reducing the frictional force between the two and improving the service life of the protrusion 122 and the guide groove 131.

[0106] Guide component 13 refers to the component that guides the movement of protrusion 122. For example... Figures 6 to 9 as well as Figure 11As shown, the guide component 13 is provided with a guide groove 131 extending along the third direction Z, and the protrusion 122 is provided in the guide groove 131. That is, the guide component 13 is a planar guide. While the guide protrusion 122 moves along the third direction Z, it drives the ejector 121 to move closer to or away from the first holding member 111 along the first direction X, thereby pushing the battery cell 7 into the cup 8.

[0107] like Figure 6 , 8 As shown in Figures 9 and 11, the guide groove 131 includes a first groove 1311. The distance between the first groove 1311 and the second holding member 112 gradually decreases along the first direction X, so that when the protrusion 122 moves in the first groove 1311, it can gradually approach the second holding member 112 along the first direction X, thereby abutting against the battery cell 7 and gradually pushing the battery cell 7 into the cup 8, ultimately realizing the feeding of the battery cell 7 into the cup 8.

[0108] By setting the guide component 13, the protrusion 122 moves along the third direction Z in the guide groove 131 and gradually approaches the battery cell 7 in the first direction X. Finally, it pushes the battery cell 7 to move along the first direction X and insert it into the cup 8, thus completing the feeding of the battery cell 7. The entire battery cell feeding device 1 has a simple structure and occupies a small area, which can effectively improve the feeding efficiency of the battery cell 7.

[0109] like Figure 4 , 5 As shown, in some embodiments, the battery cell feeding device 1 further includes a mounting member 14, a holding component 11 and a pressing component 12 are spaced apart on the mounting member 14 along a first direction X, and the pressing component 12 is movably disposed on the mounting member 14.

[0110] The holding component 11 and the mounting component 14 can be connected by detachable connection methods such as bolts or snap-fits, or by non-detachable connection methods such as welding or bonding. This application embodiment does not limit this.

[0111] The press-in component 12 is movably disposed on the mounting component 14. Specifically, a guide rail extending along the first direction X can be provided in one of the press-in component 12 and the mounting component 14, and a slider can be provided on the other. The press-in component 12 is moved relative to the mounting component 14 by moving the slider on the guide rail.

[0112] By connecting the holding component 11 and the pressing component 12 with the mounting component 14, the relative position between the pressing component 12 and the holding component 11 can be guaranteed, and the two can be set in a corresponding position in the first direction X, thereby ensuring the relative position of the battery cell 7 and the cup 8 along the first direction X and improving the accuracy of battery cell 7 feeding.

[0113] like Figure 6 , 8As shown in Figures 9 and 11, in some embodiments, the guiding component 13 further includes a first guide 132 and a second guide 133. The first guide 132 extends along a third direction Z to guide the protrusion 122 to move along the third direction Z; the second guide 133 is spaced apart from the first guide 132 in a first direction X to form a first groove 1311 between the first guide 132 and the second guide 133.

[0114] The first guide member 132 extends along the third direction Z, thereby forming a guide trajectory for the protrusion 122 to move along the third direction Z. The second guide member 133 is spaced apart from the first guide member 132 along the first direction X, thereby forming a guide groove (i.e., the first groove 1311) between the first guide member 132 and the second guide member 133. By setting the trajectory of the first groove 1311 along the first direction X and the third direction Z, the protrusion 122 can move in the guide groove 131 while simultaneously moving in the third direction Z and the first direction X. That is, the movement trajectory of the protrusion 122 in the guide groove 131 is a composite movement of its trajectory in the first direction X and the third direction Z.

[0115] As the distance between the first groove 1311 and the second holding member 112 gradually decreases along the first direction X, the surface of the first guide member 132 approaching the second guide member 133 along the third direction X gradually concaves towards the first direction X. Similarly, the surface of the second guide member 133 approaching the first guide member 132 along the third direction X gradually convexes towards the first direction X, so as to form the first groove 1311 that gradually approaches the second holding member 112.

[0116] The first guide groove 1311 is formed by setting the first guide 132 and the second guide 133. When the protrusion 122 moves along the third direction Z, it can gradually approach the second holding member 112 along the first direction under the constraint of the first guide 132 and the third guide 133, thereby inserting the battery cell 7 into the cup 8 along the first direction X.

[0117] like Figures 9 to 11 As shown, in some embodiments, the second guide 133 further includes a guide portion 1331, a floating portion 1332, and an elastic portion 1333. The guide portion 1331 is disposed corresponding to the first guide 132 along a first direction X, forming a first groove 1311 between the guide portion 1331 and the first guide 132; the guide portion 1331 is movably disposed on the floating portion 1332 along the first direction X; the elastic portion 1333 is disposed between the floating portion 1332 and the guide portion 1331, with one end of the elastic portion 1333 abutting against the floating portion 1332 and the other end abutting against the guide portion 1331.

[0118] The elastic part 1333 can be a spring or a component made of elastic material such as rubber. This application embodiment does not limit this.

[0119] The elastic part 1333 is disposed between the floating part 1332 and the guide part 1331, and its two ends abut against the floating part 1332 and the guide part 1331 respectively. When the protrusion 122 moves in the first groove 1311, it can float along the first direction X by compressing the elastic part 1333, so that when the press-in member 121 contacts the battery cell 7, it can float along the first direction X, which can avoid the rigid contact between the press-in member 121 and the battery cell 7 and damage to the battery cell 7, thereby improving the production quality of the battery cell 7.

[0120] like Figure 10 As shown, in some embodiments, the second guide 133 further includes a pressure monitoring unit 1334, which is disposed between the guide 1331 and the elastic part 1333 and is used to measure the pressure of the guide 1331.

[0121] By setting up a pressure monitoring unit 1334, when the pressing member 121 pushes the battery cell 7 into the cup 8 along the first direction X, the pushing force provided by the pressing member 121 to the battery cell 7 can be monitored, so as to prevent the battery cell 7 from being damaged by excessive pushing force and improve the quality of battery cell 7 production.

[0122] like Figure 10 As shown, in some embodiments, the cell loading device 1 includes a frame 15, and the second guide 133 further includes a guide mounting part 1335 and a drive part 1336. The guide mounting part 1335 is disposed on the frame 15, and the floating part 1332 is movably disposed on the guide mounting part 1335 along a first direction X. The drive part 1336 is drivenly connected to the floating part 1332. When the pressure of the pressure detection part 1334 exceeds a preset value, the drive part 1336 drives the floating part 1332 away from the first guide 132 along the first direction X.

[0123] The guide mounting part 1335 is disposed on the frame 15. The specific connection method between the guide mounting part 1335 and the frame 15 can be a detachable connection method such as bolt connection or snap-fit, or a non-detachable connection method such as welding or bonding. This application embodiment does not limit this.

[0124] The floating part 1332 is movably disposed on the guide mounting part 1335 along the first direction X. The movable connection between the floating part 1332 and the guide mounting part 1335 can be achieved by a guide rail slider mechanism or a lead screw mechanism, and this application embodiment does not limit this. Specifically, in some embodiments, a guide rail extending along the first direction X can be provided on the guide mounting part 1335, and a slider can be provided on the floating part 1332. The movement of the floating part 1332 relative to the guide mounting part 1335 is achieved by the movement of the slider on the guide rail.

[0125] The floating part 1332 is movably disposed on the guide mounting part 1335 along the first direction X. When the floating part 1332 moves along the first direction X, the size of the first groove 1311 can be adjusted. On the one hand, it can adapt to protrusions 122 of different specifications; on the other hand, it can adjust the driving force provided by the guide 121 to the battery cell 7 to adapt to different application scenarios.

[0126] The drive unit 1336 can be a motor, or a drive component such as an electric cylinder, pneumatic cylinder, or hydraulic cylinder; this application embodiment does not impose any limitations on this. The output end of the drive unit 1336 is connected to the floating unit 1332 to drive the floating unit 1332 to move along the first direction X, thereby adjusting the size of the first groove 1311.

[0127] In some embodiments, when the pressure of the pressure detection unit 1334 exceeds a preset value, the driving unit 1336 drives the floating unit 1332 away from the first guide member 132 along the first direction X, thereby causing the guide member 1331, the protrusion 122 and the pressing member 121 to move away from the first holding member 111 along the first direction X, reducing the pushing force of the pressing member 121 on the battery cell 7 to prevent the battery cell 7 from being damaged due to excessive pressure.

[0128] like Figure 5 , 6 As shown in Figure 9, in some embodiments, the cell feeding device 1 includes a plurality of holding components 11 and the pressing component 12, two adjacent protrusions 122 are staggered along the second direction Y, and the guiding component 13 includes two second guides 133, which are spaced apart along the second direction Y to guide two adjacent protrusions 122 respectively.

[0129] The core feeding device 1 includes multiple holding components 11 and pressing components 12. By setting multiple holding components 11 and pressing components 12, when the core feeding device 1 moves along the third direction Z, it can press the cores 7 on the multiple holding components 11 into the cup 8 in sequence under the guidance of the guide groove 131. The feeding device 1 can feed multiple cores 7 in one movement process, which improves the feeding efficiency of the cores 7.

[0130] Two adjacent protrusions 122 are staggered along the second direction Y, meaning that the distances by which two adjacent protrusions 122 protrude along the second direction Y are different. Furthermore, the guide assembly 13 includes two second guides 133 staggered along the second direction Y, allowing two adjacent protrusions 122 to move from the first grooves 1311 formed between different second guides 133 and the first guide 132, respectively. This means that the pressure of two adjacent protrusions 122 can be measured by different pressure monitoring units 1334.

[0131] When the same pressure monitoring element 1334 is used to measure the pressure on two adjacent protrusions 122, the pressure monitoring element 1334 will simultaneously measure the pressure on both protrusions 122 because the distance between the two adjacent protrusions 122 is too small, resulting in a decrease in pressure monitoring accuracy. Therefore, by staggering the two adjacent protrusions 122 along the second direction Y and using two different pressure monitoring elements 1334 for monitoring, the accuracy of pressure measurement on the protrusions 122 can be improved, thereby improving the accuracy of monitoring the driving force of the battery cell 7.

[0132] like Figure 6 , 8 As shown in 9 and 11, in some embodiments, the guide groove 131 further includes a second groove 1312 disposed downstream of the first groove 1311 along the third direction Z. The distance between the second groove 1312 and the first holding member 11 gradually increases along the first direction X, so as to guide the press-in member 121 to gradually move away from the holding member 11.

[0133] The second groove 1312 is positioned downstream of the first groove 1311 along the third direction upward Z. That is, when the protrusion 122 moves within the guide groove 131, it first passes through the first groove 1311 and then through the second groove 1312.

[0134] The distance between the second groove 1312 and the first holding member 111 gradually increases along the first direction X, so that when the protrusion 122 moves in the second groove 1312, it can gradually move away from the first holding member 111 along the first direction X, thereby separating the ejector 121 from the battery cell 7, so that the cup 8 and the battery cell 7 after the battery cell 7 is loaded can be returned to the conveying device 2.

[0135] like Figures 1 to 3 As shown in Figures 12 to 16, this application, in another aspect, provides a battery cell feeding system, including a conveying device 2, a battery cell feeding device 3, and a battery cell loading device 1. The conveying device 2 conveys a cup 8 along a preset direction; the battery cell feeding device 3 provides battery cells 7; and the battery cell loading device 1 is disposed on one side of the conveying device 2 along a second direction Y, for loading the battery cells 7 into the cup 8.

[0136] The conveying device 2 refers to the component that conveys materials. Specifically, the conveying device 2 can be a conveying component such as a belt or chain, which sequentially conveys the cups 8 to the battery cell feeding device 1 along a preset direction.

[0137] The cell feeding device 3 refers to the component used to supply the cell 7 to the cell loading device 1. Specifically, the cell feeding device 33 can be a robotic arm that transports the cell 7 to the second holding member 112 via mechanical grippers or suction components.

[0138] The battery cell feeding device 1 is disposed on one side of the conveying device 2 along the second direction Y, and is used to feed the battery cell 7 into the cup 8. Specifically, the cup 8 is clamped in the first clamping member 111 under the conveying of the conveying device 2, while the battery cell feeding device 3 provides the battery cell 7 to the battery cell feeding device 1 and is clamped on the second clamping member 112. Then, under the action of the pressing component 12 and the guiding component 13, the battery cell 7 is pressed into the cup 8 along the first direction X, thus completing the feeding of the battery cell 7 into the cup 8.

[0139] like Figure 4 , 5 As shown, in some embodiments, the cell feeding device 1 further includes a mounting member 14, with a plurality of clamping components 11 and a plurality of pressing components 12 spaced apart along a second direction X on the mounting member 14. The mounting member 14 is movably disposed on one side of the conveying device 2 along a third direction Z to sequentially convey the plurality of clamping components 11 and the plurality of pressing components 12 to the guiding component.

[0140] Multiple clamping components 11 and pressing components 12 are mounted on the mounting member 14. When the mounting member 14 moves along the third direction Z, it can drive the clamping components 11 and pressing components 12 on it to gradually approach the guide component 13 along the third direction Z. Finally, under the guidance of the guide groove 131, the battery cells 7 on the multiple clamping components 11 are pressed into the cup 8 in sequence. The loading of multiple battery cells 7 can be achieved in one movement of the mounting member 15, which improves the loading efficiency of battery cells 7.

[0141] like Figure 1 , 2 As shown in 12 to 16, in some embodiments, the cell feeding device 3 is disposed along the second direction Y on the other side of the conveying device 2 away from the cell feeding device 1. The cell feeding device 3 includes a feeding mounting member 31 and a third holding member 32. A plurality of third holding members 32 are disposed at intervals along the third direction Z, and the third holding members 32 are disposed corresponding to the second holding members 112 to provide the cell 7 to the second holding member 122.

[0142] The cell feeding device 3 is located on the other side of the conveying device 2 away from the cell loading device 1 along the second direction Y. That is, the cell feeding device 3 and the cell loading device 1 are respectively located on both sides of the conveying device 2 along the second direction Y.

[0143] Similarly, the third gripper 52 can be a mechanical claw, which opens and closes multiple movable claws to grasp and release the battery cell 7. The third gripper 52 can also be an adsorption device, which uses adsorption force to adsorb and fix the battery cell 7. It should be noted that in this case, the adsorption device can be a negative pressure device, which uses the generated negative pressure to adsorb and fix the battery cell 7. When the battery cell 7 is made of magnetic materials such as iron, the adsorption device can also be a magnetic device, which uses the magnetic force generated by an electromagnet or a permanent magnet to adsorb and fix the battery cell 7.

[0144] In some embodiments, the number of third grippers 52 is the same as the number of second grippers 112, and the spacing between each third gripper 52 along the third direction Z is also the same as the spacing between each second gripper 112 along the third direction Z, so as to ensure that each second gripper 112 has a corresponding third gripper 52, so that the battery cell feeding device 3 can provide battery cells 7 to all the second clamping members 112 in the battery cell feeding device 1 during one operation, thereby improving production efficiency.

[0145] In some embodiments, the first holding member 1111, the second holding member 112 and / or the third holding member 32 are adsorption members.

[0146] An adsorption element refers to a device that uses negative pressure generated by drawing a negative pressure or magnetic force generated by a magnetic part to adsorb and fix materials. In some embodiments, one or both of the first holding element 111, the second holding element 112 and the third clamping element 32 are adsorption elements; while in other embodiments, the first holding element 111, the second holding element 112 and the third holding element 32 are all adsorption elements.

[0147] like Figure 13 and 15 As shown, in some embodiments, the third holding member 32 is a magnetic adsorption member, and the third holding member 32 includes a receiving portion 321 and a magnetic portion 322 disposed in the receiving portion 321, and the magnetic portion 322 does not directly contact the battery cell 7.

[0148] The third holding member 32 is a magnetic adsorption member, meaning that the third holding member 32 uses the magnetic force generated by an electromagnet or a permanent magnet to adsorb and fix the battery cell 7. Specifically, the third holding member 32 includes a receiving portion 321 and a magnetic portion 3322 disposed within the receiving portion 321. By providing the receiving portion 321 to accommodate and fix the magnetic portion 322, the magnetic portion 3322 can be fixed in the third holding member 32, thereby generating a magnetic adsorption force to adsorb and fix the battery cell 7.

[0149] The magnetic part 322 is not in direct contact with the battery cell 7. That is, the receiving part 321 and the surface of the third holding member 32 holding the battery cell 7 are not connected. When the magnetic part 322 is received in the receiving part 321, there is an isolation wall between the magnetic part 322 and the surface of the third holding member 32 holding the battery cell 7.

[0150] Since the magnetic part 322 will adsorb metal dust generated during the production process, the magnetic part 322 is placed inside the receiving part 321 and is not in direct contact with the battery cell 7. This can reduce the magnetic force provided by the magnetic part 322, reduce the adsorption of metal dust, prevent metal dust from damaging the surface of the battery cell 7, and improve the production quality of the battery cell 7.

[0151] In some embodiments, the third holding member 32 includes two magnetic portions 322. The two magnetic portions 322 are respectively disposed at both ends of the third holding member 32 along the first direction X to increase the attraction force of the third holding member 32 on the battery cell 7 and prevent the battery cell 7 from falling off the third holding member 32.

[0152] like Figure 13 As shown, in some embodiments, the battery cell feeding device 3 further includes a demagnetizing component 33, which is disposed on the side of the third holding member 32 away from the battery cell 7, and the demagnetizing component 33 can move along the second Y direction to push the battery cell 7 out of the third holding member 32.

[0153] By setting up the demagnetizing component 33, when it is necessary to remove the battery cell 7 from the third holding member 32, the demagnetizing component 33 moves along the second direction Y, thereby pushing the battery cell 7 to move along the second direction Y, and finally realizing the detachment of the battery cell 7 from the third holding member 32 and its delivery to the second holding member 112.

[0154] like Figure 15 As shown, in some embodiments, the third holding part 32 is provided with a mounting hole 323 extending along the second direction Y, and the demagnetizing assembly 33 includes a push block 331, a push rod 332, and an elastic member 333. The push block 331 is disposed within the mounting hole 323; the push rod 332 passes through the third holding part 32 and is connected to the push block 331; the elastic member 333 is sleeved on the push rod 332, with one end abutting against the holding part 32 and the other end abutting against the push rod 332.

[0155] A pusher block 331 is disposed within a mounting hole 323, and a pusher rod 332 passes through a third holding member 32 and is connected to the pusher block 331. When the pusher rod 332 moves along the second direction Y, it can push the pusher block 331 to move along the second direction Y within the mounting hole 323, thereby abutting against the battery cell 7 held on the third holding member 32. When the pushing force of the pusher block 331 is greater than the magnetic force of the magnetic part 322, the battery cell 7 can be pushed out of the third holding member 32, realizing the unloading of the battery cell 7 from the third holding member 32.

[0156] The elastic element 333 can be a spring or a rubber or other elastic component; this embodiment does not limit the choice. The elastic element 333 is sleeved on the push rod 332. When the elastic element 333 is compressed, it guides and positions the elastic element 333, preventing it from detaching from the demagnetizing assembly 33. By providing the elastic element 333, it provides a buffer when the push block 331 and the battery cell 7 come into contact, preventing damage to the battery cell 7 due to excessive instantaneous pushing force. Furthermore, by providing the elastic element 333, when the external force is removed, the push rod 332 can retract under the action of the elastic force, thereby driving the push block 331 back into the mounting hole 3323, ensuring that the third holding member 32 holds and fixes the subsequent battery cell 7.

[0157] like Figure 13 As shown, in some embodiments, the demagnetizing assembly 33 further includes a demagnetizing drive unit 334, which drives the push rod 332 to move along the second direction Y to push the battery cell 7 from the third holding member 32 into the second holding member 112.

[0158] The demagnetizing drive unit 334 is positioned in the second direction Y and is corresponding to the push rod 332, thereby pushing the push rod 332 to move in the second direction Y, which in turn pushes the push block 331 to abut against the battery cell 7, thereby pushing the battery cell 7 out of the third holding member 32 and into the second holding member 112, thus completing the feeding of the battery cell 7.

[0159] In some embodiments, the demagnetizing drive unit 334 further includes a drive source and a drive unit driven by the drive source. The drive unit extends along a third direction Z. When the drive source drives the drive unit to move, the drive unit extending along the third direction can simultaneously abut against multiple push rods 332 of the demagnetizing assembly 33 to simultaneously unload the battery cells 7 from multiple third holding members 32. In this case, the drive unit can be a drive device such as an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder, and this application embodiment does not limit this.

[0160] In some embodiments, the plurality of third holding members 32 are spaced at adjustable intervals along a third direction Z.

[0161] Multiple third holding members 32 are set at adjustable intervals along the third direction Z, that is, the distance between two adjacent third holding members 32 can be adjusted. The spacing between the battery cells 7 can be adjusted during the process of providing the battery cells 7 to the battery cell feeding device 1, so as to ensure that each third holding member 32 is set in correspondence with the second holding member 112, and to ensure that the battery cells 7 on the third holding member 32 can be accurately provided to the battery cell feeding device 1.

[0162] like Figure 12 and Figure 13 As shown, in some embodiments, the battery cell feeding device 3 further includes a feeding frame 34, and the feeding mounting component 31 is rotatably disposed on the feeding frame 34 to adjust the posture of the battery cell 7.

[0163] The feeding mounting component 31 is rotatably mounted on the feeding frame 34. Specifically, the feeding mounting component 31 can be mounted on the feeding frame 34 via a rotating shaft to achieve rotation of the feeding mounting component 31 relative to the feeding frame 34.

[0164] By rotatably mounting the feeding device 31 on the feeding frame 34, when the feeding device 31 rotates relative to the feeding frame 34, the third clamping member 32 on the feeding device 31 can also rotate relative to the feeding frame 34, thereby adjusting the posture of the battery cell 7 on the third clamping member 32. For example, when the feeding device 31 rotates 90° relative to the feeding frame 34, the battery cell 7 on the third clamping member 32 can be adjusted from a vertical state to a horizontal state or from a horizontal state to a vertical state.

[0165] Since horizontal storage can lower the center of gravity of the battery cell 7 compared to vertical storage, preventing the battery cell 7 from tipping over during storage and improving the stability and safety of the battery cell 7 during storage, the battery cell 7 is usually stored horizontally in a tray. By rotatably setting the feeding mounting part 31 on the feeding frame 34, the battery cell 7 stored horizontally on the tray can be adjusted to a vertical state and then provided to the battery cell feeding device 1.

[0166] like Figure 3 and 6 As shown, in some embodiments, the conveying device 2 includes a feeding area 21 and a return component 22. The feeding area 21 is correspondingly arranged with the battery cell feeding device 1, and the guiding component 13 is arranged downstream of the feeding area 21. The return component 22 is arranged downstream of the guiding component 13 and extends along the second direction Y toward the battery cell feeding device 1 to guide the cup 8 on the battery cell feeding device 1 back to the conveying device 2.

[0167] The feeding area 21 is correspondingly set to the battery cell feeding device 1. That is, in the unloading area 21, the conveying device 2 and the battery cell feeding device 3 respectively convey the cup 8 and the battery cell to the battery cell feeding device 1. Since the guiding component 13 is set downstream of the feeding area 21, after the battery cell 7 and the cup 8 are fed to the battery cell feeding device 1 in the feeding area, the battery cell feeding device 1 moves along the third direction Z and, under the guidance of the guiding component 13, inserts the battery cell 7 into the cup 8 along the first direction X.

[0168] The return component 22 is located downstream of the guide component 13 and extends along the second direction Y towards the direction of the return component 22 and the battery cell feeding device 1. That is, after the battery cell 7 is fed into the cup 8 under the guidance of the guide component 13, it passes through the return component 22 and is guided by the return component 22 to return the cup 8 and the battery cell 7 inserted in the cup 8 back into the conveying device 2.

[0169] Specifically, the cups 8 on the conveying device 2 are first conveyed to the loading area 21. When the number of cups 8 on the loading area 21 reaches a predetermined number (the same as the number of the first holding members 111 on the cell loading device 1), the cell feeding device 3 moves along the second direction Y to push the cups 8 on the loading area 21 onto the first holding members 111 of the cell loading device 1. Subsequently, the cell loading device 1 conveys the cells 7 onto the second holding members 112 of the cell loading device 1. Finally, guided by the guiding component 13, the cells 7 are inserted into the cups 8 along the first direction, and then the cups 8 and the cells 7 inside the cups 8 are diverted back to the conveying device 2 by the return component 22 for conveying to the subsequent workstation.

[0170] like Figure 1 and 2 As shown, in some embodiments, the battery cell feeding system further includes a baffle device 4, which is located upstream of the feeding zone 21 and is used to control the number of cups 8 entering the feeding zone 21.

[0171] The blocking device 4 can cut off the channel between the upstream of the conveying device 2 and the feeding area 21, thereby controlling the number of cups 8 entering the feeding area 21. Specifically, in some embodiments, the blocking device 4 includes a blocking member and a driving member driven by the blocking member. The driving member is used to drive the blocking member to extend into or out of the conveying device 2, thereby blocking and releasing the cups 8. For example, when it is necessary to block the cups 8 from entering the feeding area 21, the driving member drives the blocking member to extend into the conveying device 2, thereby blocking the continued movement of the cups 8 inside the conveying device 2. When it is necessary to release the cups 8 from entering the feeding area 21, the driving member drives the blocking member to retract, releasing the cups 8 on the conveying device 2.

[0172] By setting the baffle device 4, the number of cups 8 entering the feeding area 21 can be precisely controlled, ensuring that the number of cups 8 pushed into the battery cell feeding device 1 by the battery cell feeding device 3 corresponds to the number of the first holding parts 111 on the battery cell feeding device 1, thus ensuring the orderly progress of the battery cell 7 unloading process.

[0173] like Figure 1 , 2 As shown in 4, 5 and 7, in some embodiments, the battery cell feeding system further includes a protective device 5. The protective device 5 includes a first protective component 51 and a second protective component 55 respectively disposed on both sides of the feeding area 21 along the second direction Z. The first protective component 51 and the second protective component 52 can move along the first direction X to prevent the cup 8 from falling from the conveying device 2.

[0174] By setting up the material protection device 5, when the material blocking device 4 is activated to convey the cups 8 to the feeding area 21, the first material protection component 51 and the second material protection component 52 rise along the first direction X and are positioned on both sides of the feeding area 21, ensuring that the cups 8 are stably stored in the feeding area 21 and will not fall off from both sides of the feeding area 21. When the number of cups 8 in the feeding area 21 reaches a preset number, the first material protection component 51 and the second material protection component 52 retract along the first direction X to below the feeding area 21, so that the cell feeding device 3 can push the cups 8 on the feeding area 21 into the first holding component 111 of the cell feeding device 1 along the second direction Y.

[0175] like Figure 16 As shown, in some embodiments, the battery cell feeding system further includes a cup-feeding device 6, which includes an inlet 61, an outlet 62, and a cup-conveying assembly 63. The outlet 62 is connected to the conveying device 2; the cup-conveying assembly 63 connects the inlet 61 and the outlet 62.

[0176] By setting up the feeding device 6, the cup 8 can be conveyed from the inlet 61 to the outlet 62, and finally fed into the conveying device 2 to complete the subsequent feeding process of the battery cell 7.

[0177] like Figure 16 As shown, in some embodiments, the conveying assembly 63 includes a feeding turntable 631, a discharging turntable 632, a transition turntable 633, and a monitoring and identification element 634. The feeding turntable 631 is correspondingly arranged to the inlet 61; the discharging turntable 632 is correspondingly arranged to the outlet 62; the transition turntable 633 is disposed between the feeding turntable 631 and the discharging turntable 632; and the monitoring and identification element 634 is disposed on one side of the transition turntable 633 for monitoring and / or identifying the cups 8 to reject unqualified cups 8.

[0178] In some embodiments, the monitoring and identification element 634 may be a CCD image recognition device to monitor the appearance quality of the cup holder 8. In other embodiments, the monitoring and identification element 634 may also be a barcode scanner to identify the QR code on the cup holder 8 to obtain information about the cup holder 8 that has passed by.

[0179] Specifically, when the cup holder 8 is being fed, the cup holder 8 first arrives at the feeding turntable 631, and then is transferred to the transition turntable 632 via the feeding turntable 631. The cup holder 8 is detected and identified on the transition turntable 632 to ensure the quality of the cup holder 8 entering the conveying device 2.

[0180] like Figure 16 As shown, in some embodiments, the cup conveying assembly 63 further includes a rejection turntable 635 disposed on one side of the unloading turntable 632 to reject unqualified cups 8.

[0181] Specifically, when the monitoring and identification component 634 detects that the cup 8 has a quality problem or that its QR code is incorrectly identified, the rejection turntable 635 will transfer the cup 8 from the feeding turntable 632 to the rejection turntable 635, and finally reject it from the feeding device 6.

[0182] like Figure 16 As shown, in some embodiments, the conveying assembly 63 further includes a rejector 636 disposed between the feeding turntable 632 and the rejector turntable 635, and the rejector 636 is movable toward the rejector turntable 635 to push the unqualified cups 8 from the feeding turntable 632 to the rejector turntable 635.

[0183] By setting up a rejection component 636, when the monitoring and identification component 634 detects that the cup 8 has a quality problem or its QR code is incorrect, the rejection component 636 will push the cup 8 from the feeding turntable 632 to the rejection turntable 635, thereby completing the rejection of the unqualified cup 8 and ensuring the production quality of the battery cell 7.

[0184] Specifically, such as Figures 1 to 16 As shown, during feeding, the cup 8 enters the feeding device 6 through the inlet 61, first reaching the feeding turntable 631, and then being conveyed to the transition turntable 632. On the transition turntable 632, the monitoring and identification component 634 detects and identifies the cup 8. When the monitoring and identification component 634 detects that the cup 8 is unqualified, the rejection component 636 pushes the cup 8 from the unloading turntable 632 to the rejection turntable 635, thereby completing the rejection of the unqualified product; when it is qualified, the cup 8 enters the conveying device 2 through the outlet through the unloading turntable 632, completing the feeding of the cup 8.

[0185] Subsequently, the cup 8 enters the feeding area 21 of the conveying device 2. When the number of cups 8 on the feeding area 21 reaches a preset value (consistent with the number of the first holding member 111), the blocking device 4 extends into the conveying device 2 to block the continued conveying of subsequent cups 8. Then, the cell feeding device 3 moves towards the cell feeding device 1 along the second direction Y, thereby pushing the cups 8 on the feeding area 21 into the cell unloading device 1 and holding and fixing them on the first holding member 111.

[0186] Subsequently, the cell feeding device 3 adsorbs the cell 7 in the tray onto the third holding member 32. The transfer mounting member 31 of the cell feeding device 3 rotates 90° relative to the frame 34, adjusting the cell 7 from a horizontal to a vertical position. Then, the demagnetizing drive unit 334 pushes the push rod 332 to compress the elastic member 333, pushing the push block 331 to gradually approach the cell 7 along the second direction Y, and abut against the cell 7. When the pushing force of the push block 331 is greater than the adsorption force of the third holding member 32, the cell 7 is detached from the third holding member 32 and pushed onto the second holding member 112, completing the feeding of the cell 7 to the cell loading device 1. Subsequently, the demagnetizing drive unit 334 retracts, and the push rod 332 returns to its initial position under the elastic force of the elastic member 333.

[0187] Next, the battery cell loading device 1 moves along the third direction Z. At this time, under the guidance of the guide groove 131, the protrusion 122 gradually approaches the first holding member 111 along the first direction X, thereby pressing the battery cell 7 on the second holding member 112 into the cup 8 along the first direction X. Subsequently, the guide groove 131 guides the protrusion 122 to gradually move away from the first holding member 111 along the first direction X, so that the ejector 121 moves away from the battery cell 7. The cup 8 and battery cell 7, having completed loading, flow back into the conveying device 2 under the action of the return member 22. This completes the entire process of unloading the battery cell 7 from the cup 8.
